As a warrior? Just melee him. Anything that isn't an artifact will be severely disenchanted, but it can be easily replaced or repaired with enchant scrolls. AC loss isn't a big deal anyway, and you have an artifact weapon. (If you had an ego weapon instead, I'd recommend avoiding the fight.)

Artifacts resist (but aren't immune to) disenchantment. You won't lose more than a few points from any of them. Also, Mim is generally encountered and killed in the midgame, so anything you're wearing then will probably be replaced before you go up against any of the really big bosses. All things considered, it's not worth worrying about the disenchantment. If you happen to have an item that grants disenchant resist around, it's worth swapping to it; otherwise, treat Mim like any other midgame unique.

It is not worth losing *any* points on a weapon to take Mim. Take him at a distance or take him with rDis or leave him alone. You'll get him later.

Ehh, if I have a good opportunity to fight him -- clear terrain, no other monsters nearby -- then it can be worth maybe losing 5% of my damage output if it means that he won't get generated again somewhere more inconvenient.

The trouble is when he chips enough of that weapon to reduce the damage giving him more time to chip. Last time I melee-d him he conveniently spawned next to a weapon with reasonable damage that I didn't want, then dropped a better weapon on death. Otherwise I wouldn't bother, he has to drop something better than your current weapon for him to be worth it.

I don't know if i was having really bad luck on Mim drops, but as shown in the screenshot in spoilers when i finally killed that unique, those "up to 4 exceptional objects" that appeared were in fact only 1 pair of steel shod boots "normal" (i mean no speed/free action/whatever brand) and with +/+ bonuses even worse than the truckloads of similar boots i already looted from my various dives.

At least i got my vengeance for past characters artifacts being ruined

Thats just luck. You still got to try. In theory Smeagol could (and should) drop The One Ring.

Afaik, uniques will drop better stuff the deeper down you are, so avoiding him until you are a few CL above his threat level should both eliminate the disenchat issue and also give you a bigger payout.

Depends on what equipment @ has. If it's not one of the end-game or mid-game artifacts, I'll risk the disenchantment. But if, for example, I've got a mage that is wielding the Trident of Wrath, I'm not risking disenchantment. I'd rather wait and take on Mim or his kin at a more opportune moment.
